The Backup DAO pairs a micro footprint with .45 ACP power, using a double-action-only trigger system and a 5+1 capacity. The matte stainless steel frame and slide offer a durable, uniform finish suited to its deep-concealment role.
Controls are streamlined with a heel-style magazine release and no external manual safety. The slide is marked with a factory warning indicating the pistol is capable of firing with the magazine removed.
Sighting is simple and snag-resistant, using fixed low-profile sights that combine a shallow rear groove (trough) with a short front blade. The slide includes rear vertical serrations for manual operation.
The 3 inch barrel incorporates a chamber witness hole for a quick visual status check. Black checkered synthetic grip panels provide a secure hold on the compact stainless frame.
This example bears the Irwindale, California roll mark associated with late AMT California production. It comes with its original factory hard case and DAO instruction manual, plus one 5-round steel magazine with witness holes.
